To all whom it may concern.-

Be it known that we, XVILLIAM OWINFIELD and JOHN F. MCNUTT, citizens of the United States, residing at WVarren, in the county of Trumbull and State of Ohio, have invented certain new and useful Improvementsin Lanterns; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled 1c in the art to which it appertains to make and use the same.

Our invention relates to improvements in lanterns; and the object of the invention is to provide a lantern with a mechanism whereby a 5 the globe may be raised and lowered with respect to the burner as occasion requires, and operated and held substantially as shown and described, and particularly pointed out in the claims. 1

The nature or principle of the invention is such that it may be represented in a great variety of different forms covering a considerable range of modifications and mechanical equivalents; but for the purposes of this ap- 2 5 plication the forms shown in the accompanying drawings are thought to be a sufficient illustration of the invention.

Thus in Figure 1 there is a plain elevation of a lantern, in which the full lines show the globe down in working position and the dotted lines show the globe raised as when the lantern is to be lighted, the wick trimmed, or the like, the difference in the two positions in a full'sized lantern being in the neighborhood of two inches, so that abundant room for these purposes is afforded. In this figure there are two spring-arms connected with the globe-rest and the side tubes, respectively, to effect the desired result, and pivoted 40 on both. Fig. 2 is a modification of this form only so faras location of the arms is concerned, the lower ends of said arms being pivoted on the guard instead of the globe-rest, and for this purpose are brought to a correspondin g1 y- 5 higher elevation. It will be understood that the guard is firmly connected with the globerest in any suitable way. Fig. 3 is a plain elevation of a lantern, illustrating still another form of operating mechanism. In this instance the spring-arms constitute the guard,

and the line of separation or pivot on the globe-rest is intermediate of the side tubes. Fig. 4 is a side elevation of a section of one of the side tubes, showing portions of the spring-arms that extend from sides opposite thereof, the same being alike on both sides of the globe, but not seen in Fig. 3, except on one side. Fig. 5 is a detail view of the ring for holding the top of the globe.

According to all the several views the globe has a vertical movement on straight or practically straight lines from one position to the other in its movements up and down, going directly up from its seat to the position shown in dotted lines and as directly down to working position shown in full lines. It is likewise held by the same agencies in both positions, so that no other means than those shown and herein described are required to keep the globe up when it is raised or to keep itdown when lowered. However, by changing the pivot-points at the tubes the arms may be employed to hold the globe-rest in a raised position only, or in a lowered position, as may be desired, and depend on other means for retaining it in the opposite positions.

It may also be stated that in all the views the following parts occur in common and form no part of this invention, except as elements in novel combinations, viz: the side tubes A, the central draft-tube B, the sliding canopy O, and the side rods D, connecting the canopy and the globe-rest E.

Referring to Fig. l, G represents springarms, so bent or formed that while one end is pivoted at g in or on the air-tube A and the other end at h on the globe-rest there will be sufficient intermediate material in the arms to cause the arms to operate as contemplated. This operation involves three features-via, 9o first, holding the globerest down on its seat, so that in the use of the lantern it will not be unseated or displaced, and in case the globe should become broken the burner remains locked in the lantern; secondly, moving the 5 globe-rest and the parts moving with it within certain definite and fixed lines up and down, so that the'globe-rest will always be automati-- eally seated when lowered to working position,

and, thirdly, holding the globe in a raised po- Ioc sition for the purpose of trimming and lighting, so that no other means than said arms or their equivalent shall be required to'perform this oifice.

In the construction shown in Fig. 1 the arms G are bent back upon themselves at one end somewhat in U form,so as to bring the bend above the pivot-point on the air-tube, while the lower end is curved slightly below the pivot-point h a portion of its length, and the .pivot h is some distance below the pivot g. Thus it occurs when the globe is raised and the pivot h passes up, say, an equal distance above the horizontal plane of pivot g, that as the said pivot hreaches the dead-center point opposite pivot g and said pivots are thus brought more nearly together a certain amount of tension is momentarily thrown into, the said arms G, and hence the said arms, eX- erting a spring-pressure, help to lift the globerest past the dead-center point and hold it in a raised position. The same action occurs when the globe is lowered to its working position, and the globe-rest is thus held securely on its seat on the cone or cap of the burner. It will be understood, however, that the form of arms shown in Fig. 1 is only one of many different forms that might be adopted. In this instance the said arms are pivoted through the side tubes and have wide bearings in the pivot It, so that the two arms will serve the purposes above named, and these arms may be single or double, as desired. Of course the pivoting in this instance and the others could be on the outside of the side tubes or on some other suitable support and be within the spirit of the invention.

The horizontal guard-wire in Fig. 1 is connected with the side wires between the globepan and canopy, or may be connected with the side tubes, and a looped stem preferably is fixed on the canopy by the side of the central draft-tube for lifting and lowering the globe and the associated parts but the lifting may be done by upward pressure on the globe-rest.

In Fig. 2 the construction of the arms is slightly different to adapt them to their position, but the effect or operation is the same.

so that they pivot on the guard instead of the globe-rest, and the U portion, extending above the pivot on the side tubes, is lengthened, while the lower portion reaching in to the guard is necessarily shortened. Otherwise the construction and operation are the same as in Fig. 1. At the top the globe is held in position by a wire ring Q, encircling the top of the globe, and having an arm g, which is pivotally attached to the edge of the canopy. Hitherto holders of this nature have been made with spring-shanks, and hence were rigid in their connections, and. in removing the globe had to be lifted by the thumb and held in a raised position until the globe was free from the lantern. To accomplish this when the globe and holder are in a heated condition is very annoying and unsatisfactory to the operator. I find that a pivoted holder operates more easily and is altogether more desirable than other styles. At the front the ring has a spring-catch q, adapted to engage the canopy and to hold the globe firmly down in position.

In Fig. 3 we have a modification of construction closely resembling that shown in Fig. 1, with the duplication of the arms G on the respective sides, and the arms in this instance forming the globe-guard. The said arms on each side extend half-way the distance from one tube to the other, and the pivot-points g and h, respectively, are at the same elevation, as shown inFig. 1. Both ends of the arms are bent downward at right an gles to the horizontal guard portion, so as to make the necessary pivot-connections, and the same action occurs, as before described, in the movements above and below the dead center. The bends in the arms at their outer ends follow the lines of and may havea bear ing against the tubes, thus forming a strong and rigid back against a blow or pressure on the guard. The position of the parts when the globe is raised is clearly seen in dotted lines. This construction may also be employed to serve as a guard for the globe only by removing the tension from the springarms and employing other well-known means for raising and lowering the globe and retainingit in its raised and lowered position.

In all these forms there is sufficient space about the guard to allow the globe to be removed or replaced by simply raising the wire loop which holds it down and taking the globe out at the side by first swinging the top outward and then removing it. The globe is replaced by a reverse movement. Of course the mechanism herein described for raising and lowering the globe Will operate just the same whether the globe is in or out of the lantern, so that the globe does notform anecessary part of the structure, and side wires connecting the globe-rest and canopy may be dispensed with by using other well-known 1 means for retaining the globe in its position. In this instance the said arms are moved up It Will be observed that the canopy, the

globe-rest, and the connecting-rods together form a frame-work for the globe which is movable as a unit up and down within the side tubes and general frame of the lantern,

the arms in all cases serving as a means of raising and lowering this frame, ashereinbefore described.

Having thus described our invention, what we claim as new, and desire to secure byLetters Patent, is-

1. In a lantern, a globe-rest having oppositely-arranged arms pivoted on fixed sup ports and at the globe-rest and constructed to form the guard for the globe, substantially as described.

2. In a lantern, a globe and a globe-rest adapted to be moved up and down in substantially direct lines, and spring-arms pivoted on fixed supports and to the globe-rest, said arms arranged to form a guard for the globe and to operate the globe-rest, substantially as described.

3. In a tubular lantern, a globe-rest adapted to be raised and lowered with respect to its seat, and pairs of guard-arms pivotally connected with said rest substantially midway between the side tubes and to fixed supports at their outer end, substantially as described.

4. A tubular lantern and a vertically-movable globe-rest, in combination with guardarms pivoted at one end on the side tubes and
